Woody Vegetation/Brush Removal

  • Change structure

  • Remove species (often invasive)

  • Grassland/Opening creation/maintenance


2
New cards

Physical Removal Techniques

  • Hand Cutting- usually requires herbicide treatment for deciduous species; usually small scale

  • Bulldozing- tends to pull roots up so no suckering, can be bad for soil

  • Masticator/Forestry Mulcher


3
New cards

Herbicide

  • Various regulations on commercial application (vary by location)

  • Two Main Types

    • Glysophate (Roundup)- both herbaceous and woody

    • Triclopyr (Garlon, Element, etc.)- woody


4
New cards

Herbicide Oil Mixes

Both types of herbicides normally (necessary for basal bark spray) mixed with oil to promote sticking to surface of treated plant

  • Nuclear Options- work well but bad for environment

    • Diesel

    • Kerosene

  • More Environmentally Friendly Options

    • Bark oil

    • Vegetable oil

    • Mineral oil

    • Methylated seed oil

    • Crop oil concentrate

Basal Bark/Band Spraying

  • Target tree size- <6 in dbh

  • Bark thickness is the more critical issue

    • Smooth, thin bark = easier to penetrate

    • Ridged, plat park = tougher to penetrate
